j 1@ j Specification of Letters Patent.

Application filed September 25, 1914.. Serial No. 86354.7".

1 b all "in/mm it may concern Be it known that I, LELAND R. ADAMS, acitizen of the United States, residing in Cliftondale, Lynn, in thecounty of Essex and State of Massachusetts, have invented an Improvementin Holding Devices for Ropes, of which the following description, inconnection with the accompanying drawings, is a specification, likecharacters on the drawings representing like parts.

This invention relates to a holding device for ropes, wires and thelike, and is especially adapted among other uses to be employed foranchoring guy and other wires employed in the overhead electric railwayequipment, telephone, telegraph and like service.

The invention has for its object to provide a simple, inexpensive andhighly efiicient device for the purpose specified.

The particular features of the invention will be pointed out in theclaims at the end of this specification.

Figure 1 represents in plan a holding device embodying this invention,with the wire cable or other rope in operative relation thereto. Fig. 2,a side elevation of the parts shown in Fig. 1. Fig. 3, a section on theline 3-3, Fig. 1. Fig. l, a section on the line d r, Fig. 1.

In the present instance, I have shown a preferred form of holding deviceembodying this invention, which consists of a metal casting comprising abar or body member (4, having at one end side arms or lugs 7) extendedsubstantially at right angles to the body member a. and provided withend flanges c, which project toward each other but are separated to forma slot (Z for the passage of the wire or rope 6 between them. The sidearms 6 are preferably provided with curved inner surfaces 10, whichconverge from the outer ends of the said arms toward the inner endsthereof, to form a chamber or passage having converging side walls, fora purpose as will be described.

The body member a is provided at its opposite end with spreading members12, 13, herein shown as cast in one piece with the body member a, saidspreading members being preferably provided with curved outer surfaces 11, 15, and with outwardly extended flanges 16, 17, which aresubstantially parallel with the body member a and form grooves for thereception of the rope c. The body member a is further provided at apoint between its ends with additional spreading members 20, 21,preferably cast in one piece with the body member a, and preferablyhaving curved outer surfaces 22, 23, (see Fig. 3), and laterallyextended flanges 24-, 25, which are substantially parallel with the bodymember a and form grooves for the reception of the rope c.

In operation with the device herein shown, the rope e is engagedtherewith, so that one portion or section of the rope crosses and restsupon another section, so that when strain is placed upon the upperportion or section of the rope, it will clamp the lower portion orsection firmly to the body member or bar a.

The rope may be engaged with the device shown in Figs. 1 and 2 in thefollowing manner. The free end 30 of the rope is first passed around thepost or other anchoring device 31 and is then passed through the slotcl, and laid in the groove 22 of the spreading member 20, and then inthe groove 15 of the spreading member 18. The portion or section 34 ofthe rope in a slack condition is then passed through the slot (Z, andlaid in the groove 23 of the spreading member 21 and in the groove 1% ofthe spreading member 12.

The end of the portion 3 of the rope is made fast, and one end of ablock and tackle (not shown) is hitched to the portion 3% of the ropebetween the fastened end and the holding device, and the other end ofsaid tackle is secured to the free end 30 of the rope 6. Strain appliedto the fall line brings the blocks together allowing section of rope 3%-to become slack, this slack moving through spreading members around post31, through spreading members until the strain of sections 3O, 34, ofrope are equal, and the block and tackle may then be removed and clampwill automatically hold. The rope does not need to be drawn to fulltension or balance to hold. In this manner, the underlying portion ofthe rope is clamped in such firm engagement with the body portion a, asto prevent slipping, and the ropeis thus secured in fixed relation tothe holding device, without the necessity of tying the free end of therope, which enables the rope to be secured at one end in a substantiallvshort time.

The converging surfaces 10 of the arm Z) serve to direct the rope to theintermediate spreading members 20, 21, so as to cause the upper or topportion of the rope to cross the lower portion at a point substantiallycentral with relation to the spreading members 20, 21 and the side arms5, and the inner surfaces 141, 15, of the spreading members 12, 13, alsoconverge to cause the upper portion of the rope to cross the lower at apoint substantially central with relation to the spreading members 12,13, and 20, 21. It is preferred to make the spreading member 12 inte ralwith the spreading member 13, and the member 20 integral with the member21, but it is not desired to limit the invention in this respect.

Claims:

1. A holding device of the character described, com rising a body memberprovided at one end with spreading members and at its opposite end withside arms havmg flanges extended toward each other to form a slot, andhaving between said parts 7 In testimony whereof, I have signed my nameto this specification in the presence of two subscribing witnesses.
